Investigation on Mechanical Properties of Self-Consolidating Concrete containing Slag Aggregate

Abstract

This paper presents the investigation results on self-consolidating concrete (SCC) produced with slag aggregate (SA). The characteristics of materials, sieve distribution of aggregates, design of self-consolidating concrete mixture and its fresh concrete properties test such as slump flow test, V-funnel, U-funnel and L-box are analyzed. The mechanical properties of SCC are with two different grades slag aggregate is tested for compressive strength (f’c), split tensile strength (fst), young’s modulus (Ec) and durability test. The investigation result on concrete mechanical properties shows that mix with larger aggregate exhibits higher values than the companion mix with smaller aggregate. Although it exhibits fairly optimum strength characteristics with slag aggregate substitution but the higher percentage of replacement affects the durability properties. This study leaves a positive way of application of slag aggregate in concrete.
